Purpose: This study was to explore barriers to effective pain management in general population. Methods: Total 163 Participants completed the Barrier Questionnaire-II (BQ-II), a 27-item on a six point scale, from May to June in 2007. BQ-II consisted of four subscales which were 1) physical effects (PE) addressing beliefs that side effects of analgesics are inevitable and concerns about tolerance, fatalism (Fa) addressing fatalistic beliefs about cancer pain and its management, Communication (Co) addressing the beliefs of 'good patient' and concerns of distracting physician from underlying disease, and harmful effects (HE) addressing fear of addiction and harmful effect to immune system of pain medicine. Results: The BQ-II total had an internal consistency of 0.877 in this study. HE was the biggest barrier (3.03) followed by PE (2.73), Fa (2.15), and Co (1.71). Items appeared as great concerns were 'there is a danger of becoming addicted to pain medication'(3.58), 'using pain medicine blocks your ability to know if you have any new pain' (3.18), 'pain medicine is very addictive' (3.09), 'when you use pain medicine your body becomes used to its effects and pretty soon it won't work any more' (3.09), and 'drowsiness from pain medicine is difficult to control' (3.09). Only 12 respondents (7.4%) reported that they took any type of pain education, however, those who took pain education represented significantly lower barriers to pain management than who did not (P=.029). Conclusion: This result suggests the strategies for public education to surmount cancer pain.

The dynamics of inorganic nutrients and phytoplankton population were examined at eight stations of Shihwa Reservoir, which situated near the cities newly constructed and the industrial complex of West-sea in Korea, from January to December 1999. Among environmental factors, average concentration of $NH_4$, SRP and SRSi were $522.7\;{\mu}g\;N/l$, $9.8\;{\mu}g\;N/l$ and $0.26\;{\mu}g\;Si/l$, respectively. Water quality was extremely deteriorated by a great amount of pollutants load into inner reservoir after the event of rainfall. Nutrients concentration was suddenly decreased toward the lower part. While $NO_3$ concentration did not much varied among stations, but it was relatively high in winter season. Chlorophyll-a concentration was high at the upper part of the reservoir, with average of $37.2\;{\mu}/l$, and closely related to the fluctuation of $NH_4$, SRP and SRSi concentrations. The phytoplankton development in the water column was dominated by diatom (autumn), prasinoid (winter) and dinoflagellate (summer). Dominant phytoplankton were composed to Skeletonema costatum of diatom, Prorocentrum minimum of dinoflagellate, Chroomonas spp. of cryptomonad, Eutreptiella gymnastica of euglenoid and Pyramimonas spp. of prasinoid. The large bloom of phytoplankton at the upper zone of the Shihwa Reservoir after inflow of a seawater were consistently observed. In consequence, water quality management of the inlet stream was assessed to be very important and urgent.

This study was carried out to estimate genetic correlations among broiler body weights for the selection of broiler breeders at early age, and to investigate the difference of growth rates between male and female in mixed-sex population of broiler from 2wks to 8 wks of age. A total of 1109 records were used in this study. the heritability estimates from combined variance components for 2-,4-, 6- and 8- weeks body weights were 0.32, 0.31, 0.35 and 0.29 respectively. Genetic correlations were 0.91 between 4wks and 8wks body weights, 0.94 between 6wks and 8wks body weights. Records obtained on 4wks and 8wks might be useful in a selection program to improve traits in 8wks broiler weight. Growth rates of male and female from nonlinear equations from 2wks to 8wks were shown differently in both linear and quadratic terms, Even though both sexes showed closely equal body weights at 2wks of age, they manifested great difference about 300g at 8wks of age. At all. ages roles were havier, grew at a faster than female. From this result it might be profitable either to select the combination of lines which has little sex effect or to rear male and female broiler separately up to the marketing body weights.

Classification of esophageal motility disorders not yet finalized and is still ongoing as the new disorders are reported, and the existing classification is changed or removed. In terms of radiology, the primary peristalsis does not exist, and the lower end of the esophagus show the smooth, tapered, beak-like appearance. The esophageal motility disorder, which mostly occurs in the smooth muscle area, show the symptoms of reduction or loss (hypomotility) or abnormal increase (hypermotility) of peristalsis of the esophagus. It is important to understand the anatomy and physiology of the esophagus for the appropriate radiological method and diagnosis. Furthermore, the symptom of the patient and the manometry finding must be closely referred for the radiological diagnosis. The lower esophageal sphincter can be normally functioning and open completely as the food moves lower. Sperandio M et al. argues that the name diffuse esophageal spasm must be changed to distal esophageal spasm (DES) as most of the spasm occurs in the distal esophagus, composed of the smooth muscle. According to Ott et al., usefulness of barium method for diagnosing the esophageal motility disorder is Achalasia 95%, DES 71% and NEMD 46%, with the overall sensitivity of 56%. However, excluding the nutcracker esophagus or nonspecific disorder which cannot be diagnosed with the radiological methods, the sensitivity increases to 89%. Using videofluoroscopy and 5 time swallows, the average sensitivity was over 90%. In conclusion, the barium method is a simple primary testing method for esophageal motility test. Using not only the image but also the videofluoroscopy with good knowledge of the anatomy and physiology, it is believed that the method will yield the accurate diagnosis.

Mediastinal tumor had been fascinated by its location on heart, great vessels, esophagus, and nervous tissue, its convenience of surgical treatment and superiority of its operative result. Between January 1989 and June 1995, eighty-seven patients with mediastinal tumor which were treated surgically in the Department of Thoracic and Cardiovascular Surgery, Asan Medical Center, School of Medicine, University of Ulsan. To provide the appropriate surgical management of mediastinal tumor, the demographic data, diagnostic evaluation, clinical presentation, location, size, operative finding and histopathologic distribution were reviewed and we analyzed relativity between invasiveness in chest computed tomographic finding or invasiveness on operative finding and histopathologic invasiveness. The anterosuperior mediastinum was the most commonly involved site of a mediastinal tumor(57%), followed by the posterior mediastinum(35%) and middle mediastinum(8%). The most frequently encountered tumors were thymic neoplasia(31%), followed by primary cyst(22%), neurogenic tumor(22%) and teratoma(10%) in decreasing order of frequency. Histopathologically invasive tumors were present in 17 patients(20%) and its site included anterosuperior mediastinum(16%) and posterior mediastinum(4%). All patients in this study underwent chest CT. In chest CT's finding, 15 patients(17%) showed invasiveness. A total excision of the tumor was performed 80 patients(92%), subtotal excision 6 patients(7%) and biopsy only 1 patient(2%). In operative finding, 14 patients(16%) were suspected invasiveness. The mean size of the tumor was 6.0$\pm$ 3.2cm. In anterosuperior mediastinum, the mean size was 6.2$\pm$3.1cm, in middle mediastinum, it was 3.9$\pm$1.1cm, in posterior mediastinum, it was 5.8$\pm$2.6cm. In malignant tumors, the mean size was 7.3$\pm$4.6cm, in benign tumor, it was 5.5$\pm$2.6cm(P<0.05). Relativity between histopathological invasiveness(17 patients) and invasiveness in chest CT's finding(15 patients) included sensitivity 35%, specificity 87% and predictability 35%, relativity between histopathological invasiveness(17 patients) and invasiveness on operative finding included sensitivity 52%, specificity 93% and predictability 64%. In conclusion, since it was proved that the compatibility of preoperative chest CT findings or operative findings and histopathological invasiveness is quite low, it is considered that wide excision of the mediastinal tumor except cystic lesion including adjacent tissues would yield better postoperative results.

This study evaluated the physicochemical and sensory characteristics of vanilla ice cream treated with gamma irradiation. The general composition of the vanilla ice cream used for the study was 45.4-53.3% moisture, 5.5-5.9% fat and 3.9-4.1% protein, and these values did not change following gamma irradiation. The Hunter L, a and b values were slightly decreased following gamma irradiation. The fatty acid composition of the ice cream included caprylic acid, capric acid, lauric acid, myristic acid, palmitic acid and stearic acid, and there was no detectable change following irradiation. There was no significant difference in TBARS (2-thiobarbituric acid reactive substances) values between non-irradiated and irradiated samples at a dose of 3 kGy or less (p<0.05). Sensory evaluation indicated that gamma-irradiated vanilla ice cream did not show any difference in color relative to non-irradiated ice cream. However, gamma irradiation did affect the flavor, taste and overall acceptability of ice cream at doses above 3 kGy. These results indicate that gamma irradiation at 3 kGy is an effective treatment for sustaining the physicochemical characteristics of vanilla ice cream with minimal changes in sensory characteristics, though further studies should be carried out to reduce the deterioration of sensory qualities induced by gamma irradiation.

This study was conducted to investigate the effects of the properties of sugar (20％, 30%) and starch (l5％, 20%, 25％) to Angdo on Angdo Pyun's preference, texture and color_ Textural characteristics were examined through sensory evaluation, Rheometer. Color test by Color and color difference meter. The properties through sensory evaluation were appearance, color, flavor, hardness, thickness and acceptability. With Rheometer, compression force, work ratio, adhesive work and gumminess were measured. With Color and Color difference meter, L, a ana b were measured. The results were as follows: 1. Sensory evaluation indicated that with the increase of starch addition, the Angdo Pyun maintained a worse apperance and got hardened and thickened. As the amount of suger increased, the Angdo fyun maintained better in color and flavor as well as its acceptability. 2. Rheometer measurement indicated that a compression force, work ratio, adhesive work and gumminess tended to increase, as the starch proportion increased. As the amount of sugar increased, the Angdo Pyun maintained a greater adhesive work, work ratio and gumminess. 3. Color and Color difference meter indicated that figure L ana a tended to increase and b, ΔE and ΔC decrease, as the starch proportion increased. 4. In the analysis of correlation between hardness and compression force, it was found that they are highly related. In view of the above results, it came to the conclusion that Angdo Pyun with the addition of 30％ sugar and 15％ starch could give the best result among the groups studied.

The purpose of this study was to analyze the importance and performance of sanitation management within childcare center foodservice facilities in Gyeongbuk province. The survey involved 248 people who participated in the food hygiene and safety education for childcare center managers in Gyeongbuk province from June to July 2010. A total of 236 survey papers were analyzed statistically by SPSS program. By the method, t-test and importance-performance analysis (IPA) was performed. Among the respondents, facility managers are 40s (41.9%) which accounted the most percentage, and for the type of facility, the largest amount was home (39.9%). The number of preschool children who are under 20 people accounted for 45.3% and food service staffs were accounted for 36.7%. No significant differences were observed for the four items on the IPA, except for the topics "the immediate deal with trash and leftover food" and "minimizing time (within 2 hours) for distribution after cooking" (p<0.001). The average score on the IPA was 4.14 points, and the average score for the importance of the evaluation was 4.49 points out of 5. Finally, childcare facility managers are aware of the importance that is lower than can be done. The results suggest that continuing education is necessary to administrators to manage the health care facility effectively.

This study was carried out to examine foodborne pathogenic contamination from 1,080 samples of cooked hams and sausages at 10 Korean processing facilities in 2010. The samples were collected from the six primary and additional sterilization products in same lot. To detect Salmonella spp., Staphylococcus aureus, Listeria monocytogenes and Clostridium perfringens in those products (n=1,080), the domestic standard method for Processing and Ingredients Specification of Livestock Products was used. As a result, Salmonella spp. was not detected in all 636 ham and 444 sausage samples. However, L. monocytogenes was detected in four (0.6%) ham and eight (1.8%) sausage samples from five manufactures. S. aureus was also only detected in 4 (0.6%) ham samples from two manufacturers, and C. perfringens was detected in 3 (0.5%) ham samples from three manufacturers, the contamination levels of these pathogens were less than 100 CFU/g. In conclusion, the results of this study indicate that the additional sterilization step of processing manufacturers could not assist to control the foodborne pathogenic bacteria.

Inflammation is a complex process involving a variety of immune cells, which defend the body from harmful stimuli. However, pro-inflammatory cytokines and inflammatory mediators can also exacerbate diseases such as cancer. Onion peel contains several phenolic compounds, including quercetin at an amount 20 times greater in peel than edible flesh. Therefore, in this study, the anti-inflammatory effects of onion peel ethanol extract (OPEE) were investigated lipopolysaccharide-induced inflammatory response. In our results, NO production decreased in a dose-dependent manner. Secretion of IL-6, $TNF-{\alpha}$, and $IL-1{\beta}$ was suppressed by 44%, 53%, and 60% respectively, at $100{\mu}g/mL$. Moreover, OPEE also suppressed expression of COX-2, iNOS, $NF-{\kappa}B$, and MAPKs in a dose-dependent manner. Formation of mice ear edema was reduced at the highest dose tested compared to the control, and reduction of ear thickness was observed in the histological analysis as well. In the acute toxicity test, no morality was observed in mice administered 5,000 mg/kg body weight of OPEE over a 2-week observation period. These results suggest that OPEE may have significant effects on inflammatory factors and be a potential anti-inflammatory material.
